FUNCTIONAL DESCRIPTION
The DP1283 is a cost effective high performance RF-Microcontroller module designed for wireless transmission
applications where the level of integration is critical.
The DP1283 highlights most of the advantages of the RF transceiver XE1283 by combining an ultra low power high
performance RF transceiver and its dedicated microcontroller on a single chip. For more information on the XE1283,
please refer to the Semtech web site:

All high and low frequencies circuits, as mentioned in the XE1283 application circuit, as well as a reference 39 MHz
crystal for the radio transceiver and a 32.768 kHz for the microcontroller are enclosed inside a shield can. The 39 MHz
crystal can also be used as a reference clock for an external application through the CLKOUT pin; the user can select
the division ratio (4,8,16 or 32) depending on its application.
The DP1283 offers the possibility to directly drive a SPI (Synchronous Peripheral Interface) interface. Two
microcontrollers ports are available, an input port (PA [0..7]) and a bidirectional port (PB [0..7]). The module
incorporates an antenna switch driven by two microcontroller pins (PB4 and PB5).
The 8-bit microcontroller embedded in the DP1283 can be programmed directly with a Semtech Prostart via the
programming pins available on the DP1283. For more information please refer to the chapter the “Programming On-
Board” chapter.
